Title: Single-phase sine wave inverter
Inventor: OKUBO KAZUO
IPC: H02M7/497
Filed: 1994-04-19
Abstract: PURPOSE:To prevent the appearance of a ripple current component included in an input power at an output side by forming a single-phase inverter of a component having an electric rating smaller than an output power. CONSTITUTION:An input DC power is converted to three or more phase AC power by a switching circuit 2 and a sine wave filter 3 formed in three or more phases. The AC power is input to a primary side of respective phases of an insulation adding transformer 4. When windings of secondary side of the transformer 4 are connected to be added, the AC power to be output from the transformer 4 becomes a single-phase sine wave AC in which power split to the three or more phases is vectorially added.

IPC: G11C11/14
Filed: 1985-04-17
Abstract: PURPOSE:To make easy the transmission of a magnetic bubble by making the form of a stretcher pattern immediately after a detector line asymmetrical. CONSTITUTION:A magnetic bubble used for detecting a signal output is attracted by an amplifier 12 comprised of a 4lambda stretcher pattern 16 immediately after a main detector line 12 and transmits successively amplifiers 11f-11h in a direction shown by an arrow P and erased by an eraser 17. In this case, the 4lambda stretcher pattern 16 immediately after the main detector line 12 is formed by an asymmetrical pattern having plural bent points in an outer configuration, so that when a rotating field HR is directed to the direction A shown by an arrow, in the lower section 16a of the stretcher pattern 16 (main detector line side 12), a magnetic bubble attracting magnetic pole + is strongly formed. Thereby, a gap transmission from the main detector line 12 can be smoothed.

Title: Variable track width type storage device
Inventor: KAMIKADO TOSHIKAZU
IPC: G11B5/09
Filed: 1989-03-30
Abstract: PURPOSE:To prevent the fall of surface recording density at an outer circumference side by providing a head moving means which moves a head to record and reproduce information on/from a recording medium and forms a track on the recording medium, and a rotary recording medium whose width of the track is different in its inner circumference side and its outer circumference side. CONSTITUTION:The head 2 is fixed to a head supporting mechanism 3 as keeping positional relation that the width direction of the head 2 is parallel with Y-axis of the diametral direction of a disk 1, and the supporting mechanism 3 is moved along Y-axis. X-axis intersects Y-axis at right angles, and this intersecting point is the innermost circumference capable of being recorded and reproduced of the area of the disk. Now, when the head is moved from the innermost circumference to the outermost circumference, a characteristic to make the track width different is obtained, and inclination becomes larger as the position of the head shifts to the outer circumference side, and the inclination becomes the maximum inclination etamax at the outermost circumference. Since the maximum track width is formed at the innermost circumference and the minimum one is formed at the outermost circumference according to the inclination between the head 2 and the head moving means 3, 4, 5, the track width can be made small at the outer circumference, and the fall of linear density at the outer circumference side can be compensated by the increase of track density.

Filed: 1999-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a reliable piezoelectric transformer by a polarization process at low application voltage by disposing a piezoelectric plate to be polarized along the polarization direction, and dividing it into a plurality of regions so that adjacent regions may overlap each other and giving a polarization process to each region along the polarization direction. SOLUTION: A plurality of polarization support electrodes 103a, 103b are disposed, being separated from each other, in the longitudinal direction of a piezoelectric plate 109. When executing each polarization process, the electrodes 103a, 103b are alternately used. Therefore, regions K1 and K2 which are to be polarized in respective polarization processes have their end parts partially overlapping each other along the longitudinal direction of the piezoelectric plate 109. In one polarization process, an end part of the polarization region is not sufficiently polarized but can be sufficiently polarized in the other polarization process. As a result, uniformed polarization can be achieved without generating the distribution in polarization.

Title: Method for shifting wavelength in semiconductor structure containing quantum well
Inventor: JIYANNIBU EMERI
IPC: H01S5/026
Filed: 1995-04-06
Abstract: PURPOSE: To shift a wavelength in a semiconductor structure with a quantum well by inducing mutual diffusion by the layer of a dielectric material that is maintained in a condensed state while being in contact with the upper surface of the semiconductor structure. CONSTITUTION: A layer 18 of a dielectric material is deposited on an upper surface 4 of a departure structure 1. The dielectric material is composed of, for example, indium. A sealing layer 20 for preventing leakage that can withstand a mutual diffusion temperature is deposited on the dielectric material layer 18. Finally, the departure structure is heated at 600-700 deg.C. The sealing layer 20 prevents the dielectric material from being evaporated at this temperature and also prevents leakage and oxidation, thus avoiding the defect of a step for including the structure in a sealed ampoule. A structure protected by the sealing layer is annealed for several times, thus obtaining the wavelength shift of a desired value accurately.  It is understood actually that the shift linearly changes as a function of total continuation time of annealing operation to be executed at a mutual diffusion temperature. Indium is formed by a uniformly thick layer.
